Over-The-Air (OTA) updates are crucial for maintaining the security and functionality of Android smartphones. While users can manually check for updates in the device’s Settings, it’s important to note that not all devices receive updates simultaneously worldwide. To help you, we regularly update our website with the latest OTA updates and offer a tutorial on how to sideload the OTA update.
There are two main (and traditional) methods for installing OTA updates on Android devices: Sideloading the OTA zip using ADB (Android Debug Bridge) and applying updates directly from the stock recovery. The first ADB method requires connecting the device to a PC, while the second recovery method is simpler but may not be available on all devices.
A new third method is also there to install OTA updates without PC on Android devices. It involves using Shizuku app and Root Activity Launcher to sideload OTA updates without needing a PC, offering a robust alternative for users. And it does not require root access.

What is Shizuku and How to Use it to Sideload OTA Update Without Root in 2025?
Shizuku is a tool that allows Android apps to access certain features of the device that usually require special permissions. It works by creating a bridge between the app and the system, enabling the app to perform tasks that it normally couldn’t do on its own. This makes it easier for users to run apps that need more control over the device without needing to root the phone. Essentially, Shizuku helps apps work better by giving them extra capabilities safely. It is also use for rooting Android devices.
In this guide, we utilize the Shizuku service to enable ADB-like functionality, allowing us to sideload the OTA update effectively and without root access.

This method utilizes Shizuku and Root Activity Launcher to install OTA updates without the need for a PC. This is the simplest approach, as it doesn’t require connecting your phone to a computer or any other device. All you need is the signed OTA update file from your manufacturer, which you should transfer to your phone’s internal storage.

1. Firs, download the OTA update bin file to your device from official sources. Ensure the downloaded file is placed in the root directory of your Internal Storage, not inside any folders.
2. Next, download Shizuku app from the Play Store or GitHub, and download Root Activity Launcher from APK Mirror.
